Letters Patent No. 114,159, dated April 25, 1871.

IMPROVEMENT IN BAND-CUTTlNG ATTACHMENTS FOR THRASHlNG-MACHINES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that we, J OHN LEE, Jr., and JOHNLEE, Sr., of Duquoin, in the county of Perry and in the State ofIllinois, have invented a certain new and useful Band-Gutter; and we dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawing andto the letters of reference marked thereon. The nature of our inventionconsists in constructing a sheaf-band cutter for thrashing-machines bymeans of a double sickle-edged reversible'circular saw or knife set on ashaft at right angles to an adjustable spring bottom or platform, onwhich the sheaf is cut, the saw or knife to pass through a slot made forthat purpose in the spring bottom when it is depressed to out the band;a foot-treadle with ratchet to depress and secure the spring bottomwhile cutting; a guard or cover on the under side of the spring bottomto shield the saw or knife when not in use; an arm or breast-guard and askeleton frame to serve as a bearing for the spring bottom; all in asuitable frame or box, two sides of which serve as bearings for thesaw-shaft, as will hereinafter more freely appear.

To enable others skilled in the art to make and use our invention, wewill now proceed more fully to describe its construction and operation.

In the drawing Figure 1 is a perspective view of our invention, onecorner of the spring bottom broken off to show the band-pulley of thesawshaft and the skeleton frame which serves as a bearing for the springbottom, and

Figure 2 is a longitudinal vertical section about the center of themachine.

A is the frame.

B is the sheaf-platform or adjustable spring bottom, secured at its rearend a to the frame A.

This platform B has side guards, b, to prevent the sheaf from fallingoff, as shown in fig. 1.

This platform may be of metalor wood, but. it must be yielding orelastic, so as to spring or bend down over the skeleton frame 0; whichis-under the platform B, when the foot-treadlc D, with rod cl, 2,connecting platform B, and treadle D is pressed down from its positionshown in fig. 2 to the position it holds in fig. l.

A slot, 0, is provided in platform B, through which the saw or knife Emay project when the platform B is depressed, as in fig. 1, for thepurpose of cutting a band.

A semicircular guard or band, F, (sec fig. 2,) is secured to the underside of the platform B and The hands need not touch the platform todepress or rest upon it, as the foot-treadle D can be used to depressthe platform, and the hands, arms, or breast can rest on the rod orguard G.

The, double sickle-edged reversible-circular saw or knife E is fitted onitsshaft e, which has hearings in the sides of the frame A, with apulley, P, on one-of its outer ends, through means of which thenecessary motion can be communicated to the saw E.

We prefer this saw, as one side will be sharpened to a desirable extentwhile the other side is in use.

The saw is placed midway of the shafts so that it will be immediatelybelow the slot 0 in the spring bottom B, and when the spring bottom B isnot depressed the saw will be out of sight; and when platform B isdepressed only so much of the saw will project above the platformas'will be necessary to cut the sheaf-band.

Our machine having been constructed as above set forth, and thenproperly connected with a thrashingmachine, and a band uniting thethrashers power to the pulley P of shaft e put on, the saw E is set inmotion; the operator having placed'a sheaf of grain on the adjustablespring platform B, with the band binding the sheaf across the slot 0,the apparatus is ready for operation.

The operator, with his hands or arms resting on the arm-guard Gr, placeshis foot on treadle D and forces it down from the position shown in fig.2 to the position shown in fig. 1, carrying the connectingrod (1 and thesheaf-platform B with it, and then fastening the treadle D in ratchet orcatch f, as rep-- resented in fig. 1.

The sheaf-platform B, as it is depressed, allows the band of the sheafto come in contact with the circular saw E, and the hand is cut. Theoperator may then, to avoidall risk, undo the treadlc D and permit thesheaf-platibrm to rise before he feeds the shcafinto the thrasher.

Our invention, thus constructed and thus operated, will effectuallyovercome the great danger attending the feeding of thrashing-machines,.which, as ordinarily constructed, have the cutters exposed oruninclosed on all sides during the whole operation of handcut-tin g. p

A hand-lever may be used instead of the trcadle D.

Having thus fully described our invention,
